A mitochondrial self-preservation mechanism
Mitochondria, the powerhouse of the cell, convert sustenance into energy, fueling the cell's activities. In addition to power, mitochondria also produce reactive oxygen species, byproduct molecules primed to help facilitate communication among the ot.....»»
Study uncovers low-temperature deformation mechanism of pure titanium
Titanium (Ti), often hailed as the wonder metal for its remarkable properties, has many applications in aerospace, marine, and biomedicine industries. Known for their low density, high strength, high ductility, great corrosion resistance, and excelle.....»»
Researchers discover important membrane transport mechanism in pathogenic bacteria
Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial membrane. Like a forklift, a soluble protein outside t.....»»
Metal-organic frameworks study unravels mechanism for capturing water from air
Researchers from the Helmholtz-Zentrum Dresden-Rossendorf and Dresden University of Technology have unraveled the water adsorption mechanism in certain microporous materials—so-called hierarchical metal-organic frameworks (MOFs)—while probing the.....»»
Battling persistence in tuberculosis bacteria
Researchers at the Indian Institute of Science (IISc), in collaboration with NCBS and InStem, have uncovered an important mechanism that allows the tuberculosis (TB) bacterium to persist in the human host for decades. They found that a single gene in.....»»
3D preservation of trilobite soft tissues sheds light on convergent evolution of defensive enrollment
They'd been in the collections of the Harvard Museum of Comparative Zoology (MCZ) since the 1870s when they were first discovered. Nestled in among the largest collection of trilobites, the unique fossils rested in drawers until 145 years later when.....»»
Unveiling the role of autophagy in metabolism and growth for tomato fruit development
Autophagy, a eukaryotic mechanism for breaking down cellular components, is a vital process in lytic organelles such as vacuoles in yeast and plants, and lysosomes in animals. Research has predominantly focused on the model plant Arabidopsis, reveali.....»»
Viral enhancement of nanomaterial cancer sensor improves early detection
Researchers from SUTD have developed an advanced system of breast cancer cell detection with improved speed and sensitivity, using a viral mechanism to enhance the tool's sensing accuracy......»»
A mechanism of pressure-induced glass phase transition leading to advanced phase-change memories
When temperature or pressure is applied to a material, its state changes from liquid to solid or remains solid but exhibits structural changes. This change is called a phase transition or change......»»
Researchers discover a mechanism that controls the identity of stem cells
Researchers at the University of California, Irvine, discovered a mechanism that controls the identity of stem cells. When this mechanism fails, embryonic stem cells revert back in time and become totipotent......»»
A sun protection mechanism helps plants to survive
Just as people can get sunburned, plants can also suffer from too much sunlight. To stay healthy, they use an internal "sun protection mechanism." Pierrick Bru, a Ph.D. student working with Alizée Malnoë at Umeå Plant Science Centre and Umeå Univ.....»»
A theoretical approach to ferroelectricity in hafnia-related materials
Hafnia ferroelectrics are based on their technical promise and remarkable behaviors, where the peculiarities stem from an active extrinsic mechanism that contributes to their properties from a growing number of new intrinsic features......»»
Laser-induced hydrothermal growth for electrocatalytic applications
In the new study published in the journal International Journal of Extreme Manufacturing on 1 November 2023, researchers from the UK and China reported a novel technique based on a laser-induced hydrothermal reaction (LIHR) mechanism for the growth o.....»»
Research reveals clever dosage control mechanism of biallelic genes
Have you ever wondered why we carry two copies of each chromosome in all of our cells? During reproduction, we receive one from each of our parents. This means that we also receive two copies, or alleles, of each gene—one allele per chromosome or p.....»»
Plants found to recruit distinct chemical activities of coumarins under different soil pHs
Plants have two main uptake mechanisms to obtain iron (Fe) from the soils. The type of strategy employed depends on the botanical classification of the plant. In the so-called strategy-I mechanism, plants must first reduce the trivalent iron (Fe3+) i.....»»
Study show extracellular vesicles can also deliver messages from non-human cells
Messenger bubbles produced by human cells can pick up bacterial products and deliver them to other cells, University of Connecticut researchers report in the Nov. 16 issue of Nature Cell Biology. The discovery may explain a key mechanism by which ba.....»»
Unlocking long-term genetic memory: Dormant bacterial spores offer key insights into evolutionary survival strategies
A recent study spearheaded by Prof. Sigal Ben Yehuda and her team at Hebrew University has unveiled a captivating facet of bacterial dormancy. Their research illuminates the mechanism through which dormant bacterial spores uphold and activate an endu.....»»
The role of malate decarboxylate CsNADP-ME2 in mediating the balance of carbon and amino acid metabolism in fruit
Central metabolism produces carbohydrates and amino acids that are tightly correlated to plant growth and thereby crop productivity. Malate is reported to link mitochondrial respiratory metabolism with cytosolic biosynthetic pathways. Although the fu.....»»
Researchers identify "unicorn" defense mechanism that protects bacteria from antibiotics
Researchers at McMaster University have discovered unique characteristics of a mechanism used by bacteria to resist an important class of antibiotics. The new research, published in Nature Chemical Biology, shows that resistance to aminoglycoside dru.....»»
Combining extreme-ultraviolet light sources to resolve a quantum mechanical dissociation mechanism in oxygen molecules
For the first time, researchers have succeeded in selectively exciting a molecule using a combination of two extreme-ultraviolet light sources and causing the molecule to dissociate while tracking it over time. This is another step towards specific q.....»»
Study sheds new light on mechanism of robust motility of flagellated bacteria
Flagellated bacteria are propelled by the rotation of helical flagellar filaments, each with a flagellar motor at its base. Taking Escherichia coli (E. coli) as an example, each cell has 3–7 flagella whose rotation as a helical bundle enables the c.....»»
